“…Other reflections such as (1 0 1), (1 0 4) and (1 1 0) are very weak or cannot be observed in the XRD spectrum due to the strong reflection peaks from the Au substrate. [13,14]. From the cross-sectional view of the film on the SiO 2 /Si substrate, the film thickness is estimated to be about 500 nm.…”

The capability of fast charge and fast discharge is highly desirable for the electrode materials used in supercapacitors and lithium ion batteries. In this article, we report a simple strategy to considerably improve the high rate capability of Co 3 O 4 nanowire array electrodes by uniformly loading Ag nanoparticles onto the surfaces of the Co 3 O 4 nanowires via the silver-mirror reaction. The highly electrically conductive silver nanoparticles function as a network for the facile transport of electrons between the current collectors (Ti substrates) and the Co 3 O 4 active materials. High capacity as well as remarkable rate capability has been achieved through this simple approach. Such novel Co 3 O 4 -Ag composite nanowire array electrodes have great potential for practical applications in pseudo-type supercapacitors as well as in lithium ion batteries.

Li Ni 0.8 Co 0.15 Al 0.05 O 2 thin films were prepared by pulsed-laser deposition at varying growth conditions. It was found that the growth and microstructure of the films is highly dependent on the target composition, deposition temperature, and the reactive atmosphere during laser ablation. The x-ray diffraction and Raman spectroscopic measurements indicated the high-structural quality of the grown LiNi0.8Co0.15Al0.05O2 thin films. A phase diagram mapping the effect of temperature on the microstructure of LiNi0.8Co0.15Al0.05O2 thin films has been proposed. The measurements of charge-discharge profiles of Li microcells using the LiNi0.8Co0.15Al0.05O2 films grown at 450°C demonstrate their possible applications in microbatteries. A stable capacity of 98μAh∕cm2μm was obtained in the potential range of 4.2–2.5V for LiNi0.8Co0.15Al0.05O2 films grown at 450°C.
